CABLE HOISTING AND CONVEYlNG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 566,849, datedSeptember 1, 1896.

Application filed January 2, 1896. Serial No. 574,146. (No model.)

Be it known that I, WILHELM DiisEDAU, a citizen of Prussia, residing atTrenton,in the county of Mercer and State of New Jersey, have inventedcertain new and useful improvements in C ble Hoisting and ConveyingApparatuses, of which the following is a specification, reference beinghad therein to the accompanying drawings.

My invention relates to that particular class of cable hoisting andconveying apparatuses in which there is used a suspended carrying-cable,upon which travels a suspended carriage that is moved by a haulingrope,and attached to said carriage is another rope that is known as thehoisting-rope. In operation the carriage moves out upon thecarrying-cable by motion imparted to it by the hauling-rope, and as thecarriage moves out upon the carrying-cable there trails along after itthe hoistingrope. Should any considerable strain be put upon thehoistingrope, itwould interfere with lowering the load. Hence thehoisting-rope is always a slack rope, sagging considerably. Asheretofore such cableways could not be operated without supports for thehoisting rope. Hence, prior to my invention, it has been absolutelynecessary to use carriers to support the hoisting-rope. Upon thesecarriers solely depend the operation of the cableway, and theyfrequently become deranged, cansing great damage in some instances, anda suspension of the working of the line until they are repaired.

The object of my invention is to avoid the use of these carriers by theemployment of a carriage with hoisting-gear driven by an endless rope,and when self-dumping is required with two independent hoisting-gearsdriven by two endless ropes.

The conditions and the special devices and arrangements I have fullyexplained hereinafter and have illustrated in the accompanying drawings,in which- Figures 1 and represent in side elevation a generalview of myinvention. Fig. 3shows in side elevation the carriage on a larger scale.Fig. i shows a section at line 1 to 2 of Fig. 3; Fig. 5, a section atline 2 to 3 of the same. Fig. 6 shows in side elevation a form of thecarriage adapted to dump a skip or load. Fig. 7 shows a section at line5 to 6 oi Fig. 6.

The carriage, Fig. 3, has a suitable frame A, on the upper part of whichare journaled grooved wheels 13 B, which run one behind the other on thecable a. Suspended in the frame below is the grooved sheave C, and fixedto this sheave is the drum D. hoisting-rope 7) is wound upon the sheaveC sufficiently to secure the required friction. The fall-rope (Z windsitself upon drum D with one end, and the other end is carried over afall-block E, up around another sheave F in the frame A, thence down tothe strap of block E, thus giving three parts to the fallrope cl tosuspend the load. .More or less parts can be used by varying the numberof sheaves E and F. Any exertion of hoistingrope I) will be transmittedto fall-rope 01 through sheave C and drum D. The fallroped will wind orunwind upon drum D, and thus raise or lower the load, which will besuspended by the hook of fall-block E.

The carriage, Figs. 6 and 7, has two independent hoisting-gears, eachone consisting of the same parts as that shown in Fig. 3. Twohoisting-ropes b and b" are necessary. The hoisting-rope b winds uponthe grooved sheave O, and the hoisting-rope b" Winds upon the sheave C".Fall-block E is suspended by fall rope d, and fall-block E" is suspendedby fallrope d". The skip or bucket will be suspended at one end by ahook of the fall-block E and the other end by hookof the fall-block E.

The cable hoisting and conveying apparatus shown in Fig. 1 consists ofthe supporting-cable a, the endless hoisting-rope I), and thehauling-rope c. The cable is stretched and supported in the usualmanner, and the hauling-rope being connected to the carriage at one endruns over sheave g, around driving-drum O, thence over sheaves K, M, andN, and being connected to the carriage at the other end. The arrangementof this rope is as heretofore employed. The hoisting-rope being endlessis wound upon the grooved sheave C sufficiently to secure the requiredfriction. The hoisting-rope extends in both direct-ions from thehoisting-sheave G to the sheaves H and L at the ends of the way, at oneend going around sheave L and returning The over sheave K at the other"end of the way and down the driving-drum I. The drivingdrums O and Pmay be of any suitable construction.

The cable hoisting and conveying apparatus shown in Fig. 2 has twoendless hoistingropes b and b. It will be understood that thehoisting-ropes b and b are wound upon hoisting-sheaves C and C,respectively, of

the carriage and are operated separately by means of independentdriving-drums P and Q. The advantage of the two endless hoisting-ropes band b and duplicate hoistingsheaves C and O and hoisting-drum D and Dwith their fall-ropes d and d and fallblocks E and E is an importantone, and with them the skip or bucket is under perfect control. By aneven pull upon the two ropes the bucket may be raised, and then by anuneven pull may be dumped at the will of the operator at thehoisting-machine. The hooks on the lower side of the fall-blocks E E areshown for connection with the skip or load.

With this arrangement the endless hoistingrope is maintained constantlytaut, and the hoisting and lowering of a load are not afiected by thesag of the hoisting-rope, and I am enabled entirely to dispense with.the carriers for the hoisting-rope always used prior to my invention inconnection with hoisting-ropes of cable hoisting and conveyingapparatuses.

I claim- 1. In a cable hoisting and conveying apparatus the combinationWith a carrying-cable; of a carriage depending therefrom; a hauling-ropeto move the carriage back and forth; and an endless rope for hoisting orlowering the load.

2. In a cable hoisting and conveying apparatus the combination with acarrying-cable; of a carriage depending therefrom, and provided withhoisting-gear for hoisting and lowering a load; a hauling-rope to movethe carriage back and forth; and an endless hoisting-rope,to impartmotion to said gear.

3. In a cable hoisting and conveying apparatus the combination with acarrying-cable; of a carriage depending therefrom, and provided with twoindependent hoisting-gears for hoisting and lowering a skip or loadwhereby said skip can be tripped by hoisting one end higher than theother; a hauling-rope to move the carriage back and forth; and twoendless hoisting-ropes to impart motion to said gears.

4. In a cable hoisting and conveying apparatus, a carriage havinggrooved wheels arranged to run upon said cable, said carriage dependingtherefrom, a hoisting-sheave in the carriage-frame below the cable, saidsheave being connected with the hoisting-drum, a fall-rope, ahauling-rope, and an endless hoistingrope below the cable and wound uponthe hoisting-sheave, and mechanism for operating the hoisting andhauling ropes, the parts being combined and operating, substantially asdescribed.

5. In a cable hoisting and conveying apparatus, a carriage havinggrooved wheels arranged to run upon said cable, said carriage dependingtherefrom, a hauling-rope, two independent hoisting-sheaves in thecarriage below the cable, said sheaves being connected withhoisting-drums, two fall-ropes, and two endless hoisting-ropes each oneconnected with a hoisting-sheave below the cable and mechanism foroperating the ropes, the parts being combined and operatingsubstantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
